this is a scale native to the Middle East which was used by the famous surf guitarist Dick Dale.

it is essentially a Major scale with a flatted 2nd and a flatted 6th.a similar scale to this (it is the same scale but with a dominant seventh) has already been posted as an 'Arabic' scale. I don't mean to say that the 'Arabic' scale is wrong. I have never been taught that particular scale but I am guessing it is also a commonly used scale in the Middle East. this is just another one.
